Resumo: 
Candid#1 is the first live attenuated vaccine produced and registered in Argentina. Produced since 2003 at the INEVH to prevent Argentine hemorrhagic fever, it is obtained by harvesting supernatants of diploid cells infected with an attenuated strain of Junin virus and subsequent lyophilization. The stability of this vaccine is crucial to ensure its effectiveness. This study was aimed to evaluate the stability of Candid#1 by exposing it to different time and temperature conditions. Three vaccine batches produced in 2003 were analysed according to the following storage scheme: (a) reconstituted vaccine at 2 °C to 8 °C for 8 days; (b) lyophilized vaccine at 2 °C to 8 °C for 6 months; (c) lyophilized vaccine at -18 °C to -20 °C for 10 years. The potency was assessed in Vero cell monolayers under agar. The results were: (a) reconstituted vaccine was stable between 2 °C and 8 °C for 8 days, (b) lyophilized vaccine was stable between 2 °C and 8 °C for 2 months, and (c) lyophilized vaccine was stable 9 years between -18 °C and -20 °C, keeping all its properties. These results allowed us to establish the following storage conditions and expiration times for Candid#1: (a) reconstituted: 12 hours between 2 °C and 8 °C, (b) lyophilized: 30 days between 2 °C and 8 °C and (c) lyophilized: 9 years between -18 °C and -20 °C. Based on our results, favorable changes were made in the conditions of transport, storage and distribution of the vaccine. Domestic freezers in strategically located centers were installed, allowing the preservation of vaccine stocks for distribution to secondary vaccination centers.
